Online visitors can see it. #* Thus begins a multi-line comment. Online visitors wont see this text because the Velocity Templating Engine will ignore it. *# Here is text outside the multi-line comment; it is visible. 在使用Velocity引擎解析上面的模板时输出的结果是 This is text that is outside the multi-line comment. Online visitors can see it. Here is text outside the multi-line comment; it is visible. 可以看到多行注释内的内容是不会输出的。 下面的例子阐明了注释的用法 This text is visible. ## This text is not. This text is visible. This text is visible. #* This text, as part of a multi-line comment, is not visible. This text is not visible; it is also part of the multi-line comment. This text still not visible. *# This text is outside the comment, so it is visible. ## This text is not visible. 用Velocity引擎解析上面的模板输出的结果是 This text is visible. This text is visible. This text is visible. This text is outside the comment, so it is visible. 在VTL中还有第三种注释VTL注释块。VTL注释块用来保存如文档的作者、版本号等信息。例如 #** This is a VTL comment block and may be used to store such information as the document author and versioning information: author version 5 *# 转载于:https://www.cnblogs.com/toSeeMyDream/p/5574805.html
